SSL_CTX_ctrl(3SSL) OpenSSL SSL_CTX_ctrl(3SSL)NAME
SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl - internal handling functions for SSL_CTX and SSL objects
long SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg);
long SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)());
long SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg);
long SSL_callback_ctrl(SSL *, int cmd, void (*fp)());
The SSL_*_ctrl() family of functions is used to manipulate settings of the SSL_CTX and SSL objects. Depending on the command cmd the
arguments larg, parg, or fp are evaluated. These functions should never be called directly. All functionalities needed are made available
via other functions or macros.
The return values of the SSL*_ctrl() functions depend on the command supplied via the cmd parameter.

SSL_CTX_set_ssl_version(3SSL) OpenSSL SSL_CTX_set_ssl_version(3SSL)NAME
SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method - choose a new TLS/SSL method
int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
const SSL_METHOD *SSL_get_ssl_method(SSL *ssl);
SSL_CTX_set_ssl_version() sets a new default TLS/SSL method for SSL objects newly created from this ctx. SSL objects already created with
SSL_new(3) are not affected, except when SSL_clear(3) is being called.
SSL_set_ssl_method() sets a new TLS/SSL method for a particular ssl object. It may be reset, when SSL_clear() is called.
SSL_get_ssl_method() returns a function pointer to the TLS/SSL method set in ssl.
The available method choices are described in SSL_CTX_new(3).
When SSL_clear(3) is called and no session is connected to an SSL object, the method of the SSL object is reset to the method currently set
in the corresponding SSL_CTX object.
The following return values can occur for SSL_CTX_set_ssl_version() and SSL_set_ssl_method():
0 The new choice failed, check the error stack to find out the reason.
1 The operation succeeded.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
